When I interview creatives, I often ask them what advice they would give to the next generation, the up-and-comers. Curiously, there’s one incredibly important habit that nearly all of them possess that is almost never mentioned. So what is the secret ingredient in their productivity regime? It’s simple: They get up early.

...

If you’re getting up early, you probably already have a good idea of what you want to accomplish that day – otherwise it would be hard to motivate to get up in the first place. Being an early riser also indicates a natural affinity for ritual and discipline – both key traits of especially productive people.

Here’s none other than Ernest Hemingway on the merits of getting up early:

When I am working on a book or story I write every morning as soon after first light as possible. There is no one to disturb you and it is cool or cold and you come to your work and warm as you write… You write until you come to a place where you still have your juice and you know what will happen next and you stop and try to live through until the next day when you hit it again. You have started at six in the morning, say, and may go on until noon or be through before that. When you stop you are as empty, and at the same time never empty but filling, as when you have made love to someone you love. Nothing can hurt you, nothing can happen, nothing means anything until the next day when you do it again. It is the wait until the next day that is hard to get through.
